.SH DESCRIPTION
.LP
The \fBgetaudit()\fR function gets the audit \fBID\fR, the preselection mask,
the terminal \fBID\fR and the audit session \fBID\fR for the current process.
.sp
.LP
The \fBgetaudit()\fR function can fail and return an \fBE2BIG\fR errno if the
address field in the terminal \fBID\fR is larger than 32 bits. In this case,
\fBgetaudit_addr()\fR should be used.
.sp
.LP
The \fBsetaudit()\fR function sets the audit \fBID\fR, the preselection mask,
the terminal \fBID\fR and the audit session \fBID\fR for the current process.
.sp
.LP
The \fBgetaudit_addr()\fR function returns a variable length
\fBauditinfo_addr\fR structure that contains the audit \fBID\fR, the
preselection mask, the terminal \fBID\fR, and the audit session \fBID\fR for
the current process. The terminal \fBID\fR contains a size field that indicates
the size of the network address.
.sp
.LP
The \fBsetaudit_addr()\fR function sets the audit \fBID\fR, the preselection
mask, the terminal \fBID\fR, and  the audit session \fBID\fR for the current
process. The values are taken from the variable length structure
\fBauditinfo_addr\fR. The terminal \fBID\fR contains a size field that
indicates the size of the network address.
.sp
.LP
The \fBauditinfo\fR structure is used to pass the process audit information and
contains the following members:
.sp
.in +2
.nf
au_id_t     ai_auid;        /* audit user ID */
au_mask_t   ai_mask;        /* preselection mask */
au_tid_t    ai_termid;      /* terminal ID */
au_asid_t   ai_asid;        /* audit session ID */
.fi
.in -2

.sp
.LP
The \fBauditinfo_addr\fR structure is used to pass the process audit
information and contains the following members:
.sp
.in +2
.nf
au_id_t        ai_auid;      /* audit user ID */
au_mask_t      ai_mask;      /* preselection mask */
au_tid_addr_t  ai_termid;    /* terminal ID */
au_asid_t      ai_asid;      /* audit session ID */
.fi
.in -2

.SH RETURN VALUES
.LP
Upon successful completion, \fBgetaudit()\fR and  \fBsetaudit()\fR return
\fB0\fR. Otherwise, \fB\(mi1\fR is returned and \fBerrno\fR is set to indicate
the error.
.SH ERRORS
.LP
The \fBgetaudit()\fR and \fBsetaudit()\fR functions will fail if:
.sp
.ne 2
.na
\fB\fBEFAULT\fR\fR
.ad
.RS 10n
The \fIinfo\fR parameter points outside the process's allocated address space.
.RE

.sp
.ne 2
.na
\fB\fBEPERM\fR\fR
.ad
.RS 10n
The {\fBPRIV_SYS_AUDIT\fR} privilege is not asserted in the effective set of
the calling process.
.RE

.SH USAGE
.LP
The calling process must have the {\fBPRIV_SYS_AUDIT\fR} privilege asserted in
its effective set.
